We report new preliminary B Physics results obtained with 300,000 hadronic Z0 decays collected by the SLD experiment at the SLC between 1993 and 1997. Three analyses are presented: a measurement of B+ and B0 lifetimes, a study of the time…
We report a new measurement of A_b using data obtained by SLD in 1997-98. This measurement uses a vertex tag technique, where the selection of a b hemisphere is based on the reconstructed mass of the bottom hadron decay vertex. The method…
